Finding a Trustworthy Heat Pump Installer in Leicester

Last reviewed: 2 October 2026

With free council funding and the £7,500 grant both available, Leicester homeowners are a target for misleading sales calls as well as genuine offers. This guide explains how to tell them apart and choose an installer you can trust.

Bay-fronted Victorian terraces along a wide Leicester street — the city's most common home for a heat pump conversion.

Why it matters who you choose

A heat pump is a 15–20 year investment. A good installer designs it to keep your home warm cheaply; a poor one can leave you with cold rooms and high bills. And because there’s real money available — the £7,500 Boiler Upgrade Scheme, and Leicester City Council’s free Warm Homes funding — there are also people trying to cash in.

Genuine offers vs scams

Genuine:

  • Boiler Upgrade Scheme: you choose an MCS-certified installer, they survey your home, quote with £7,500 deducted, and apply to Ofgem.
  • Warm Homes: Local Grant: run by Leicester City Council for households with an income under £36,000 in homes rated EPC D to G. You apply through the council’s scheme, which arranges the assessment and installers.

Be suspicious of:

  • cold calls, texts or doorstep visits offering a “free government heat pump”
  • anyone asking for personal or bank details to “check eligibility” on the phone
  • pressure to sign on the day
  • a company that won’t give a name and address you can check

If an offer of free work seems to come from the council, contact Leicester City Council directly using the details on its own website to confirm.

What MCS certification gives you

MCS (the Microgeneration Certification Scheme) certifies renewable heating installers against standards for design, installation and commissioning. Certification:

  • is required for the grant, and since 28 April 2026 that’s set in law
  • underpins the noise calculation that keeps most installations within permitted development
  • requires membership of a consumer code (RECC or HIES), giving you rules on contracts, deposits and complaints

Check the company on the MCS installer search on the MCS website, and make sure the name matches your quote.

Ten questions for a Leicester installer

  1. How many heat pumps have you fitted in the past year, and in what kinds of homes?
  2. Have you converted Victorian terraces like mine? Can I speak to one of those customers?
  3. Will you calculate heat loss room by room?
  4. What flow temperature will you design for?
  5. Which radiators need replacing?
  6. Have you checked for microbore pipework?
  7. Where will the cylinder go — and could the cellar work?
  8. Does the noise calculation pass at my neighbour’s window?
  9. How will you deal with Leicester’s hard water?
  10. What deposit do you take, and is there an insurance-backed guarantee?

What a good quote looks like

  • whole-house heat loss and design temperature
  • heat pump model and size
  • a room-by-room radiator schedule
  • cylinder size and position
  • outdoor unit position and noise figure
  • electrical work
  • the £7,500 grant shown as a deduction (or £9,000 for oil and LPG homes, on applications from 21 July 2026 to 31 March 2027)

Our hidden costs guide lists questions that bring out anything missing.

After installation

You should receive the MCS certificate, warranty registration, commissioning records and a walk-through of the controls. Ask about a follow-up visit after the first cold spell to fine-tune settings. Annual servicing keeps the system efficient and the warranty valid.
